    Abstract: 岩石節理面係由許多大小不等之起伏狀節瘤組合而成,本文以傅立葉級數觀念將節理面分解成一系列之週期函數,再以前5階週期函數疊加模擬只含主要節瘤之二維與三維節理面、以前40階函數疊加模擬含主要節瘤加次要節瘤之節理面。並以2D及3D石膏模擬試體進行高低應力下之直剪試驗,期比較主要節瘤與次要節瘤在不同應力環境下、不同維度下剪力行為之異同。文中並將層狀成形法(LOM)應用於3D節理表面模型之仿製上,亦利用雷射剖面儀之預定量測軌跡功能,使其可以簡易以電熱絲切割珍珠板,以製作2D節理剖面模具。
    The roughness of rock joints is consisting of many sized asperities and divided into the primary asperity and secondary asperity. This paper used the method superimposing five and forty components of sine-shaped sub-profiles with different wavelengths and amplitudes to simulate two smoother and rougher joint profiles, respectively. The 2D model profile is cut using the laser profilometer and 3D joint surface is generated using the LOM (Laminated object manufacturing). The aim of this study is to clarify the difference of primary and secondary asperity on 2D profile and 3D surface.
